Javascript How To Filter Array Of Nested Objects With Unknown Depth This guide will walk you through how to filter arrays of objects with nested arrays, using practical examples and clear explanations. by the end, you’ll be able to confidently handle even the most deeply nested data structures. Suppose we have an array of user objects, each containing a nested address object with a city property. our goal is to filter this array to keep only the first occurrence of users from each unique city. Recipes.filter(r => r.ingredients.some(i => i.ingredient === enteredvalue)); this gets all items in recipes where at least one item in ingredients has a value for ingredient that is equal to enteredvalue. I would like to filter out objects from the full list where at least one of selectedids values appears in the object's item's id array. var selectedids = {'1', '9', '45', .}; and then add them to the tmp list. i tried using filters but i failed to figure it out completely. thank you. var tmp = full list.filter(function (obj) {.

For efficiency reasons, filter first so that you don't map elements you are not interested in. don't use semicolons in js. they are not needed and it gets inconsistent if you forget them somewhere but the program still works. you can also use destructuring of the arguments to get rid of the dummy i. also prefer strict comparison.
